Anodized CNC Machining Parts Custom Manufacturing

Anodized CNC machining parts are precision-machined aluminium components that receive an electrochemical surface treatment after machining. The anodising process creates a durable oxide layer that improves corrosion resistance, wear performance, and surface hardness. This makes the parts suitable for demanding industrial, aerospace, electronics, EV, and automotive applications where both dimensional accuracy and surface durability matter.

Type II anodising is a standard anodic coating used to improve corrosion resistance and appearance, while Type III hard anodise creates a thicker, harder surface for higher wear resistance. Type II is often chosen for general industrial and cosmetic applications. Type III is better suited for precision components exposed to friction, repeated handling, or more demanding operating environments.

Anodising is primarily used on aluminium parts, making it a strong fit for custom CNC machined aluminium components. Marcus machines aluminium along with zinc and magnesium, but anodising specifically applies to aluminium surfaces. Material selection depends on the part's structural, weight, corrosion, and finishing requirements, especially for applications in aerospace, electronics, EV, and industrial manufacturing.

Marcus operates more than 20 in-house CNC machining centres including 3, 4, and 5 axis equipment, Turn-Mill centres, and Drill-Tap centres. Precision machining is performed to tolerances of ±0.005mm on critical features such as mating faces, bearing bores, threaded interfaces, and sealing surfaces. Custom jigs and datum-based setups help maintain repeatability across production runs.

Yes. Marcus provides in-house CNC machining along with in-house surface treatment capabilities, including anodising, so customers can source finished parts through a single manufacturing partner. This integrated workflow reduces outsourcing delays, improves process control, and helps maintain consistency from machining through pre-treatment, finishing, inspection, and shipment.

Marcus operates under IATF 16949:2016 and ISO 9001 certified processes. Quality support includes DFM review, APQP, PPAP, FAIR inspection, inline inspection, advanced metrology including CMM, and batch-level documentation for applicable finishing processes. This structured quality framework helps customers receive traceable, repeatable, and production-ready parts for regulated and performance-critical applications.

Yes. Marcus supports both low-volume prototype requirements and ongoing production programmes. The company offers rapid prototyping support through CNC machining and structured new product development processes, then scales into repeatable manufacturing using dedicated tooling, validated setups, and controlled inspection methods. This helps customers move from development to production with fewer supplier transitions.

Marcus serves a broad range of sectors including automotive, EV, aerospace, electronics, healthcare, energy, and industrial manufacturing. These industries often require tight tolerances, durable finishes, and dependable documentation. By combining machining, anodising, finishing, and engineering support, Marcus can supply custom parts suited to both functional and appearance-critical applications.
